CD54HC157F TI Logic Multiplexer | 2-Input, 4-Bit, High-Speed CMOS

Product Overview

The CD54HC157F is a high-speed CMOS logic quad 2-input multiplexer from Texas Instruments. It selects one of two 4-bit data sources (A or B) based on a common select input (S). The device features buffered outputs and a strobe (active-low enable) input. It operates over a wide voltage range of 2V to 6V and is characterized for operation from -55°C to +125°C. The CD54HC157F is ideal for data routing, signal gating, and bus selection in industrial, automotive, and communication systems.
